为构建飞行员头部关联传递函数测量所需要的声学环境,提出用于飞行员头部关联传递函数测量的半消声室设计指标,并采用新型平板式复合吸声结构进行半消声室的设计和建造。所设计的半消声室在有限的建筑空间内达到自由声场空间的最大化和关键声学指标的最优化。半消声室建成并经过检测鉴定后,各项指标达到相关标准要求,某些关键指标优于设计要求。建成的半消声室提供飞行员头部关联传递函数测量需要自由声场环境,可以满足实验测量的需要。
為構建飛行員頭部關聯傳遞函數測量所需要的聲學環境,提齣用于飛行員頭部關聯傳遞函數測量的半消聲室設計指標,併採用新型平闆式複閤吸聲結構進行半消聲室的設計和建造。所設計的半消聲室在有限的建築空間內達到自由聲場空間的最大化和關鍵聲學指標的最優化。半消聲室建成併經過檢測鑒定後,各項指標達到相關標準要求,某些關鍵指標優于設計要求。建成的半消聲室提供飛行員頭部關聯傳遞函數測量需要自由聲場環境,可以滿足實驗測量的需要。

In order to provide an acoustic environment for measurement of pilot’s head relation transfer function (HRTF), the design indexes of hemi-anechoic room were proposed, and a new compound panel absorber was employed for design and re-construction of the hemi-anechoic room. According to the design, space of the free acoustic field of the hemi-anechoic room can reach the maximum and the key acoustic indexes are optimized within the limited room. The appraisal of NIM after the completion of the hemi-anechoic room showed that all of the indexes satisfy the demand of the corresponding standard and some key indexes are even better than those in the design. The hemi-anechoic room can furnish a free acoustic environment for HRTF measurement.
